填充題he....a policeman

如果係曾經係policeman,就用was,即past tense,因為佢依家已經唔係警察,用present tense即代表現在是policeman,即代表事實。
如果依家都做緊policeman,咁就要用is,因為呢個係事實!!!
但呢題係沒前因後果,所以用2個皆可!

是否用在死去的人要用past tense啊？
如 Mr. Chan was a man and he was died.
這是對的,因為他現在不是人,這並不是事實,他只是曾經是人,所以用past tense!

Past tense 用係　過去　既事情
He was a policeman.
即係．．　佢曾經係個警察。　〔冇講係咪死左〕

He is a policeman.
佢係個警察。

I finished my homework yesterday.
我昨日完成了功課。

Present tense 用於 fact (事實)
^好少用其實.. 雖然最簡單
eg.
Do you like the Spiderman?
The sun rises from east.
The girl always wears a dress to date with her boyfriend.
